Record Sheets: Phoenix Upgrades is a record sheet compilation available in .pdf format through BattleCorps. The companion to Technical Readout: Project Phoenix, RS:PU contains the record sheets for all the units and variants described in that book. In addition, following the release of Total Warfare, new variants were added to this release that incorporated weapons and equipment that were first introduced in that book, as well as some that were made tournament-legal by their inclusion in it. Included in this update was a foreword by then-line developer Randall N. Bills that explained why the Unseen became the Unseen, the first time an official broke the silence about the decision.
